anyone else noticed that the past few days, there is a noticeable reduction in the rewards payment? my hashrate use to be around 6.2gh/s, now it dropped to about 5.3gh/s. i understand that the hashing power calculated by this pool is sometimes not accurate, but this is a drop of nearly 1gh/s, which is pretty significant. and also, the "24 hour luck" stats has been in the negatives for the past week. i use to get around 3-4 BTC per day, now i'm down to around 1.3 to 2 BTC per day.

what's up with this noticeable drop? did anything happen to server or were there any updates to the pool's mining algorithms?
